PIN DESCRIPTION, REQUIRED EXTERNAL COMPONENTS
SLVS606C – SEPTEMBER 2005 – REVISED FEBRUARY 2007
NAME
PIN
I/O
DESCRIPTION
EXTERNAL REQUIRED COMPONENTS
(SEE APPLICATION DIAGRAM)
AC
7
I
Adapter charge input voltage, connect to
1-
F (minimum) capacitor to AGND1 pin to minimize
AC_DC adapter positive output terminal
overvoltage transients during AC power hot-plug events.
(dc voltage)
ADC_REF
22
I/O
ADC internal reference filter or ADC
4.7-
F (minimum) to 10-F (maximum) capacitor connected to
external reference input
AGND2 pin
AGND0
16
–
Analog ground connection
Connect to analog ground plane
AGND1
48
–
Analog ground pin
Connect to analog ground plane

Analog ground pin
Connect to analog ground plane
ANLG1
24
I
Analog input to ADC, programmable
Can be used to monitor additional system or pack parameters
current source output
ANLG2
23
I
Analog input to ADC, programmable
Can be used to monitor additional system or pack parameters
current source output
BAT
17,
I/O
Battery power
Connect to battery positive terminal. Connect 10-
F capacitor
18
(minimum) from BAT pin to AGND1 pin.
BLUE
1
O
Programmable blue driver, open-drain
Connect to BLUE input of RGB LED
output, current sink output when active.
DPPM
14
I
Dynamic power path management
External resistor from DPPM pin to AGND1 pin sets the DPPM
set-point
regulation threshold. 1-nF (minimum) capacitor to from DPPM
to AGND1 sets BAT to OUT short-circuit blanking delay when
battery is hot-plugged into system.
FB3
41
I/O
White LED duty cycle switch output, LED
External resistor from FB3 pin to PGND3 pin sets LED peak
current setting
current. Connect 100-pF (minimum) filter capacitor to PGND3
pin.
GPIO1
43
I/O

I/O Example: Set SM1 and SM2 converters in standby mode
GPIO3
54
I/O
General purpose programmable I/O
Example: ADC conversion start trigger
GREEN
56
O
Programmable LED driver, open drain
Connect to GREEN input of RGB LED
output, current sink output when active.
